Tantalum Plate (Ta Plate)

Tantalum has a melting point exceeded only by tungsten & rhenium. Edgetech Industries LLC can furnish tantalum plate and tantalum tungsten plate, tantalum niobium plates with 2000mm maximum length.

Major use for tantalum is in the production of electronic components, mainly capacitors and some high-power resistors. Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer. The dielectric layer of tantalum capacitor can be very thin, a high capacitance can be achieved in a small volume. Tantalum capacitors are attractive for cell phones, computers, and automotive electronics for its size and weight advanctages. Due to its high melting point and oxidation resistance tantalum is used in the production of insulation barriers in vacuum furnaces. Since it resists attack by body fluids and is nonirritating, tantalum is widely used in making surgical instruments and implants. For example, porous tantalum coatings are used in the construction of orthopedic implants due to its ability to form a direct bond to hard tissue.

We provide tantalum plate (Ta plate) with following dimensions and specifications:
Product: Tantalum Plate (Ta plates, tantalum plating, tantalum board)
Specification: ASTM B708
Material: R05200, R05400, Ta-Nb3, Ta-Nb20, Ta-2.5W (R05252), Ta-10W
Size: 5.0-10.0mm Thick x 30-1000mm width x < 2000m L

Thicker tantalum will be named as tantalum block.
